PA with writing skills, efficient at searching the web, organized.

I'm currently fundraising and need a PA to help me stay on top of things and deal with a lot of the grinding tasks.

I would need you to help me manage a variety of tasks to lighten my work load which include:

Opening and managing a FB/Twitter account
writing and updating copy to my website
(also proofreading things I have written to the website)
Online research, and phone calls
Sometimes online shopping (amazon etc.)or personal shopping
Other tasks as they come up.

You need to be very organized and efficient, as I need help in various areas.

Huge plus if you have a technical flare and can help me manage my WordPress site. Also a plus if you have ever worked with charities.

Very helpful if you live in London and can actually come in once or twice a week.

Intensive work for the next 2 weeks, and then down to just a few hours a week.
